Self-consistent Seeding of the Interchange Instability in Dipolarization Fronts [PDF]

, 2011
We report a 3D magnetohydrodynamics simulation that studies the formation of dipolarization fronts during magnetotail reconnection. The crucial new feature uncovered in the present 3D simulation is that the process of reconnection produces flux ropes ...

A phenology-based vegetation index classification (PVC) algorithm for coastal salt marshes using Landsat 8 images

International Journal of Applied Earth Observations and Geoinformation, 2022
Coastal salt marshes, as a globally significant intertidal ecosystem, are highly productive but extremely fragile and unstable. Mapping coastal salt marshes accurately is the basis of assessing global climate change, biological invasion, and coastal ...

Effect of Gate Oxide and Back Oxide Materials on Self-Heating Effect in FinFET

East European Journal of Physics
The self-heating effect on the fin field effect transistor (FinFET) is investigated. The dependence of the lattice temperature in the channel center of the transistor on the thickness of the gate oxide, as well as the back oxide, is simulated.
